You know personally I don’t like any quality of seemingly arbitrary stratification between people because of graffiti or street art. Skill and what not should be applauded and valued certainly, but security and talent needs no elitism to bolster itself.
I think graffiti and street at works best when it creates connections,fosters intimacy with our immediate environment and subverts alienation. Not when skilled but emotionally fragile people use it to prop themselves up over others. Agape not celebrity.
